Selene was sitting in the parlor of Rarity’s studio as the white unicorn walked in front of her humming. Twilight was panicking beside Selene as Discord was floating around in the air. Applejack was looking towards Rainbow who was staring at herself in the mirror. She had a long dark blue shark’s tail with light pastel rainbow fins. Pinkie was standing beside her as a pink clownfish giggling as she played with her mane. Fluttershy hid beside Applejack as she watched Rarity pace in the workroom.

“We need to make her not look like Selene” Rarity smiled as her eyes settled on the hair dye. She had a smile as she placed a towel around her gills keeping them covered as she pulled Selene’s mane back. Using her magic Rarity pulled a black hair dye from her shelf as she moved it towards Selene. The merpony sat silently as Kibby walked in rubbing her head. Discord glanced towards her as he sealed up the door behind her.

“So?” Twilight spoke up as Kibby looked towards her.

“Celestia can try and stop the purity check, however, your relationship will come out in the open. He might push for something that is out of her control” Kibby looked towards Twilight as Selene looked over at her.

“So what is a purity check?” Applejack looked towards Selene as she started to turn red.

“A purity check is when one royal or merpony has a nurse to look up my marehood to see if I did not roll in the kelp” Selene was sputtering out her words as the others stare at her in disbelief. She stayed still as Rarity pulled on her mane trying to place the dye on.

“They want to open you… and look to see if you haven’t been with a pony?” Applejack tilted her hat as she looked towards the others.

“That’s just”

“Bullocks!” Rarity shouted as the dye simply slid off of Selene’s mane creating a mess on the floor.

“Its tradition for a royal mare to go through. The first time I didn’t half to go through with it because I was young and my guards were always around. Ra and Za could vouch for me not being with any pony. Now that I am away from home and I do not have my guards it's custom for it. But I see one problem”

“What is that Selene?” Kibby looked up at her as she pointed towards her tail.

“My tail. If the nurse that my brother brought is real then all she has to do is noticed”

“Your tail is wider and longer than a normal merpony that is not carrying” Kibby groaned as she rubbed her eyes “We half to hide your tail. I will head back to Canterlot and talk to the princesses some more. If something changes for the worse I will send Krill with a guard” she turned and walked out of the room causing Selene to sigh.

“I am so doomed” she hung her head causing the others to stare back at her.

“Now it's not that bad” Pinkie moved towards Selene.

“Orion is the last brother I want to see. He is the third born while Saluki is the second born and Stratus is the firstborn. Orion is head of the military and guard of all the cities or kingdoms that merge with Maremuda. He can not be overruled with what he does to the guard. Only my father can overrule him” she moved her fins as she sighed.

“So?” Rainbow looked towards her.

“The guard liked to corner me and gang up on me with the nobles. My brother would let them”

“That is so”

“Idiotic!” Pinkie huffed as Selene nodded. She had a smile on her face as Rarity was cleaning up the dye from her fur. Walking to the back of her workroom Rarity walked back carrying a sweater in her hooves.

“I created a new sweater for you. It's supposed to get cold tonight and its Nightmare Night” she squealed holding the sweater up. It was a black sweater with grey bats and small pumpkins along the bottom. Selene slipped the sweater on. Her fins were nestled together softly as she moved them a bit. Rarity fixed her mane up before placing a hat on her head causing her to look up.

“So tonight is Nightmare Night? What are we going to do then?” she turned to look at Twilight.

“Well depending on how cold it gets I was thinking about taking Spike around to collect candy” she smiled as Selene looked towards Twilight.

“Sounds like fun”

“Good, we can then meet the girls in the middle of town. Princess Luna should be here tonight as well” She had a smile as Selene looked towards Rarity. She pulled out a purple necklace with a dark purple diamond in the middle. Small lighter amethyst sitting on either side of the shell.

“Oh dearie you didn’t” Rarity held up the necklace as she moved towards Applejack holding up another necklace. It was a light yellow shell with an orange diamond surrounded by two red diamonds.

“I couldn’t sleep last night so I was working on your necklaces. Their like twilight's they will let you have a merpony tail and allow you to swim underwater” she was blushing as she looked towards the others. Rarity was smiling as she placed the necklace on. Applejack slipped it over her hand allowing it to rest on her shoulders.

“Oh this is lovely” Rarity smiled as she looked at it in the mirror. She tapped on the shell causing her hind legs to turn into a long white tail with purple spots. Her fins were the same color of her mane as she moved her tail “I’m a”

“Catfish merpony. They are very graceful and are known in the merpony world as a rare catch as the stallions call it. But most of the noble wives are catfish merponies” Selene noticed Rarity’s eyes lighting up.

“I’m model after a nobles wife” she was smiling as Selene nodded slowly. She clapped her hooves together as Selene looked back towards Twilight.

“I am going to take her back to the treehouse” Twilight picked Selene up in her magic walking out of the boutique. Selene looked down towards Twilight noticing a worried look on her face.

“Twilight?” Selene spoke up causing the purple unicorn to stop. She placed Selene on the ground next to her.

“I’m thinking would it be best if we could hide you” Her eyes adverted from Selene causing the merpony’s ears to flatten against her head.

“Should I just hide somewhere other than my tank? I can take a train to the Crystal Empire. Or I could return to the islands” she looked down at her hooves “That would be the best. My brothers don’t know about the islands” her hooves were shaking as Twilight sighed.

“I am going to write a letter.” She hung her head as she walked towards the library in silence. Selene watched her as she followed behind her mind filled with places she could hide. Once she got to the library she noticed Twilight instantly went up to the second floor leaving her alone with Spike.

“Is everything alright?” he looked up from his book noticing the look on Selene’s face.

“Yes… so what costume are you going to wear tonight” she forced a smile on her face as Spike got to his feet smiling.

“I was going to go as a knight in shining armor” he gave her a pose as Selene walked over and patted his head.

“How long will it take for you to get it on?” she watched his face drop as he ran towards the stairs.

“It’s going to take me hours” he rushed out of her sight leaving Selene alone with her thoughts.

“If they touch you I will be pissed” Star spoke up as Selene sighed. She moved over to the couch leaning against it.

“Star, please. I don’t need my magic seals breaking”

“I know but still” Star groaned as Selene closed her eyes leaning her head against the couch behind her. Looking towards the door she noticed ponies were still coming in looking at the books on the shelves. Moving from the couch Selene sat behind the counter taking not on the books that were being taken out. Her hooves were shaking as she heard the door open up. Lifting her head she noticed Kibby walking in with Krill by her side.

“I thought you were my brothers” she let the breath she was holding go. Krill shook his head as he walked towards Selene.

“We came to see how you were doing. Kibby told me what your brothers want. But she also told me you were using your magic” he looked up at her as Selene nodded. She pulled her magic revealing her stomach was larger than what she was showing. Her ears folded back on her head as she looked down towards her stomach.

“I wanted to go out and have fun. I don’t want the others to change plans just for me” she closed her eyes as she heard hoof steps stopping. Looking up she noticed Twilight standing at the bottom of the stairs staring at her. Spike was wearing half his costume looking at her in shock.

“I was going to say. Cadence will let you stay in the empire” she walked towards Selene placing a hoof on her stomach “I didn’t think you were this large” her eyes glanced towards Selene's stomach. It was the size of a small bowling ball.

“She is carrying twins Twilight. She will be larger than normal. I am worried about how she will be. Princess Celestia and her brothers will be here tonight to do the purity check. I came early to see if Selene is under stress”

“How do you know if she is under stress?” Spike looked up towards the healer as Kibby started to blush.

“Can he handle adult”

“Spike go and put the rest of your costume on. I want to see it please” Selene smiled as Spike nodded. He ran upstairs causing Selene to move her sweater a bit. Kibby ran her hoof down from her waist towards Selene’s slit.

“See how the scales around here are moving revealing her marehood. This should happen a month before giving birth. If her scales are moving this fast it means she is under stress.”

“And?” Twilight looked towards Kibby.

“It means I can probably push the purity test back”

“Who is doing the check?” Selene looked towards Kibby as she looked away.

“Are you allergic to anything?”

“I’m allergic to eel, snapper, brown kelp, mangos, pecans, and yellowfin” she looked towards Kibby who had a smile on her face.

“You just saved your own tail” she snickered.

“Why?” Twilight looked towards Kibby.

“The Nurse is an eel. If she touches Selene or enters her marehood. Selene will break out and enter shock.”

“But my brothers are still an issue”

“If Twilight is in the room in her merpony form. I do not think your brothers will be a problem. Especially if Celestia vouches for Twilight as a national hero.” Krill looked towards the healer as Spike ran down wearing his armor. He had a small cape attached to his back causing Selene to smile towards him.

“Look at the knight and shining armor” she smiled as she moved from the stool she was sitting on. After pulling her spell off it was getting harder for her to move around with her stomach.

“So is tonight canceled?” Spike spoke up “I promised the Cutie Mark crusaders I would go with them” he kicked his foot on the ground causing his armor to ding. Selene shook her head.

“I don’t see why your night should be canceled” she turned to look at Twilight who had a smile.

“Tonight Spike why don’t you go by yourself. Just promise me you will not let the cutie mark crusaders pull you into any stunt” she groaned as Spike’s face lit up.

“I promise” he grabbed the pillowcase he had on the floor. He ran out of the library smiling Krill placed on hoof around Selene as Kibby did the same on the other side.

“Let's get you upstairs where you can rest easily” They started to move towards the stairs before Twilight used her magic to pick them up. She shook her head as she carried them up the stairs placing them in the middle of the bedroom. Selene pulled her sweater off allowing Kibby a better view of her stomach. The healer walked around using her magic to do a simple scan while Twilight placed pillows around keeping her propped up.

“You're doing fine. No more magic” Kibby glared towards her as Selene looked away from her “Keep it up and I will get an anti-magic device from Celestia and Luna” that caused Selene to gulped as she looked towards the healer. Krill had a smile on his face as he laid beside Selene’s head.

“So have you chose any names yet?”

“Well, no…we haven’t talked about them yet. But I was thinking about Lunar Dusk and Celestial Dawn or Celestial Twilight” she smiled seeing Twilight stop in her tracks. She turned towards Selene with a weird look in her eyes.

“Really?”

“Well, what do you want to name them” Selene’s tail moved a bit as she looked over at Twilight. The unicorn sighed as she rubbed the back of her neck.

“I haven’t thought of any names. I have been busy” she was blushing as Selene smiled.

“Well think about it. Are you going to hand out candy?” she sat up as Twilight nodded.

“I was going to go and meet with the girls in the middle of town”

“Go” Selene stopped her as she waved her hoof. Twilight turned towards her with a weird look on her eyes.

“You’re sure?”

“Twilight, please. My aunts will be here when it is dark” she smiled as the purple unicorn nodded.

“I will see if Pinkie will get me some cupcakes to bring back” she moved from the bookshelf walking out of the room leaving Selene alone with Kibby and Krill. Krill was working on a class schedule and some projects while Kibby was working on Selene’s tail and gills causing the merpony to jump.

“Kibby warning” she glanced back at the pony behind her.

“Sorry” she rolled her eyes as Selene sat there going over the same plan with Krill. It was a simple lesson plan where Selene would be teaching some of the scholars about the different island ponies and what they normally do. She would also go over which island did what and what they would eat and how they interacted with others. The sun was setting making way for the moon as Twilight walked back with a plate of cupcakes and Fluttershy.

“Fluttershy? I thought you would be out and about tonight?”

“I don’t like Nightmare night” her voice was soft as she moved over to Selene noticing her stomach “I didn’t think you were that far along” her wings were fluffed up as Selene smiled.

“I was hiding my stomach with my magic” Selene pulled a pillow closer to her as Twilight placed he cupcakes on a desk. The door opened up as two guards one dressed in gold and one in silver walked in standing by the door. Princess Celestia walked in with her brothers silently following behind her. A random dark green merpony with a slimy grass green mane and tail walked in smiling. She had an eel tail as she laid out in front of Selene. After them, Princess Luna walked in wearing fangs and a cape as the others were dressed up as well.

“Nightmare Night is upon us!” she shouted causing Fluttershy to run and hide. Celestia was busy staring at Selene as well as the others as the merpony smiled.

“Sister you ate a melon from water” Stratus spoke up as Selene glared at him.

“The reason I am larger now for most of you. Is that I hid my stomach with magic. I wanted to hang out with you all I did” she looked up at them as Pinkie huffed and waved her hoof towards her.

“You are resting from this point on. Auntie Pinkie will make sure of it” she smiled as Selene laughed a bit. The eel looked towards Selene before looking to the princes.

“I am Unagi King Orion’s nurse. But from what I see a purity check is not in order anymore” she looked towards them as Orion walked over.

“And why not?” he tilted his head glare towards his nurse. He did not see Twilight placing her tail on and move over to Selene. She pulled her tail up behind her making it hidden as she rested her chin on Selene’s side watching.

“She is with eggs”

“And allergic to eels” Kibby spoke up causing Orion to turn towards her.

“Then you will do it”

“Orion you stubborn fool. I am with eggs and a mate” Selene hissed causing her brother to stare at her.

“Father and the others may say you have the sea gem. However, I do not see one on you” he huffed as he glared towards Selene “And till I do you are the only daughter of King Triton and must act like it”

“My gem is on my back” she moved a bit as she leaned forward revealing the gem. She heard a huff as she laid back out allowing Twilight to rest her head again.

“You may carry a sea gem. You may be the queen but you must be pure for your mate. And if you have one where is he” he glared towards Selene as she pointed towards Twilight.

“My mate is behind me”

“A unicorn…a random unicorn?” he had a chuckle as Celestia looked towards Orion.

“That unicorn is my student. She has defended Equestira many times. She is a hero to us all along with her friends” Celestia and Selene noticed Orion backing off as he nodded.

“Fine but she still has to be tested. Her mate is a member of Equestria but my sister is a member of the sea. She still has to follow the rules.” At this time his eyes widen as Twilight moved from her stop standing over Selene with her fins stretched out wide and her tail moving behind her.

“I think this is the one time you are defeated brother” Stratus walked up towards him as he placed his hoof on Orion’s shoulder.

“Very well at least she has chosen well. A national hero will be good for her” he stuck his head up as Selene looked towards him.

“I will say this now dear brother. You are a tyrant Orion and to my other brothers. I will not return to the sea. Once the peace treaty is signed I am no longer a member of the sea. I will be a member of Equestria and under the Lunar house” she watched as her brothers stared at her in shock. Selene’s heart was racing in her chest as she could feel star moving in the shadows grumbling. She knew this night would not end well as her brothers all started to complain.
